Through Hole Assembly (THT)

Reliable component strength for demanding applications

Through Hole Assembly

Through Hole Assembly

Our Through Hole Assembly service provides the mechanical strength and durability required for ruggedised electronics, high-power components, and mission-critical performance. We support both prototype builds and ongoing batch production, delivering solder-secure connections that stand up to vibration, heat, and real-world stress.

THT Assembly for When Reliability Matters Most

Through-hole technology remains the preferred solution for applications where long-term reliability is essential — such as:

  • Power conditioners and high-current circuits
  • Industrial machinery and control systems
  • Transportation and automotive electronics
  • Aerospace and defence-grade assemblies

All components are hand-placed by trained operators for maximum control, ensuring strong solder joints and consistently high assembly quality.

And when your project requires a combination of durability and compact design, we can fully integrate Through Hole + Surface Mount components as part of our wider PCB assembly capability.

Our Through Hole Capabilities

We support:

  • Mounting for connectors, relays, capacitors & transformers
  • Mixed-technology builds (THT + SMT)
  • Lead-free RoHS-compliant soldering
  • Traditional soldering where required
  • No-clean or water-wash solder processes
  • Assembly to IPC-A-610 standards

Whether you’re improving an existing design or launching a new system, we adapt the assembly process to suit your application and lifetime requirements.

Through-Hole Assembly FAQs

Quick answers to help you understand how we support your THT requirements.

Through-hole soldering provides stronger mechanical bonds and higher tolerance to vibration, heat, and impact — making it ideal for power components, connectors, and ruggedised electronics.

Larger and high-power parts such as transformers, relays, connectors, switches, and electrolytic capacitors benefit most from through-hole mounting because they need secure, reinforced attachment.

Yes — where required, we follow strict build processes aligned to IPC-A-610 standards and can discuss additional requirements for aerospace, defence, and industrial certification needs.

Hand assembly is standard for precision, but we can incorporate selective or wave soldering depending on the component type, batch size, and design constraints.

Absolutely — mixed-technology assemblies are very common. We handle full PCB assembly, so THT and SMT stages are completed in one workflow.

Yes — we can review your layout, recommend improvements for manufacturability, and help ensure the right balance of performance, cost, and durability.
